To avoid readback of the register values in case integration time, gain or scale is queried, save the register values. Use the saved values to report the correct scale value. v2: removed redundant parenthesis, add missing spaces Stefan Brüns (4): iio: light: vl6180: Move range check to integration time setter, cleanup iio: light: vl6180: Avoid readback of integration time register iio: light: vl6180: Cleanup als_gain lookup, avoid register readback iio: light: vl6180: Correct ALS scale for non-default gain/integration time drivers/iio/light/vl6180.c | 125 +++++++++++++++++++++++++-------------------- 1 file changed, 69 insertions(+), 56 deletions(-) -- 2.14.1
